Mumbai, Jan 11 (Agencies): The Indian rupee gained 12 paise to Rs 45.33 against the US dollar in early trade at the Interbank Foreign Exchange on Tuesday, supported by a higher opening in the stock market and weakness of the American currency against other major currencies.

The rupee had depreciated by 7 paise against the US currency to close at a fresh three-week low of Rs 45.45/46 in the previous session on Monday following fall in equities.
